Choose the best Lewis structure for BF₃.

Question

Quizplus · Accepted Answer

The best Lewis structure for BF₃ is the one with the least formal charges on atoms. In option B, all atoms have a formal charge of zero except for the sulfur atom which has a formal charge of -1. Option A has a formal charge of +1 on the boron atom and option C has a formal charge of +1 on the fluorine atom, both of which are less desirable than having a -1 formal charge on sulfur. Option D has a formal charge of +1 on the boron atom and a formal charge of -2 on the sulfur atom, which is not as stable as having a -1 formal charge on sulfur. Option E has a formal charge of -2 on the boron atom and a formal charge of +1 on the sulfur atom, which is also less stable than option B. Therefore, option B is the best choice for the Lewis structure of BF₃.
